中文摘要：
考虑初态He原子电子间的关联效应、末态敲出电子与剩余束缚电子间的关联效应和末态屏蔽效应，计算和分析了在共面、大能量损失和小动量转移这一特殊几何条件下730ev电子离化He原子的三重微分截面．所得结果与Stevenson等人的相对实验数据和CCC理论计算结果进行比较发现：所得到的理论曲线能够反映实验数据给出的三重微分截面的结构特征．
英文摘要：
Both initial-state correlation effect between electrons of helium, final-state correlation effect between ejected electron and remaining bound electron and final-state screening effect have been considered. The triple differential cross sections for ionization of helium by 730 eV electron are calculated and analyzed in the special geometry of coplanar, large energy loss and small momentum transfer. The present results are compared with the relative experimental data and CCC theoretical calculations from Stevenson et al. It was found that the present results give a better description for the structure of the triple differential cross sections from experimental data.
